GHAIN-CONVEYER FLIGHT.

To all whom it may concern:

Be it known that I, JAMES wW. TURNER, a citizen of the United States, residing at New Orleans, parish of Orleans, State of Louisiana., have invented a certain new and useful Improvement in Chain-Conveyer Flights, of which the following is a full, clear, and eXact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a top plan view of a trough with the conveyer chain shown therein and which chain is equipped with flights of my improved construction. Fig. 2 is a cross section taken on the line 2-2 of Fig. l. Fig. 3 is a rear elevation of the central portion of al flight of my improved construction. Fig.4isaplan view of the central portion of the flight. Fig. 5 is an enlarged cross section taken on the line 5 5 of Fig. 1. Fig. 6 is a section taken on the line 6-6 of Fig. 3. Fig. 7 is a cross section taken on the line 7 7 of Fig. 5.

My invention relates generally to chain conveyers of the type particularly designed for use in carrying off refuse lumber from saw mills, and the like, and more particularly to the flights or cleats which are applied to the chain, and which ride upon the bottoni of the trough and convey the refuse lumber, saw dust, etc., therefrom.

The principal object of my invention is to provide a flight which is an improvement upon the forms of flights shown in Patents Nos. 627,482, 943,734 and 977 ,273, and further to provide a two-'part flight which can be readily attached to the chain, and which extends laterally in both directions from the link to which it is attached.

A further object of my invention is to provide a two-part flight which can be easily and quickly positioned upon a link of the conveyer chain by slightly twisting said chain and partially rotating one of the parts of the flight with respect to the opposite part, and to form the joint between the two parts so that when said parts are properly assembled there will be absolutely no lost motion or play between them, and they will combine to form in eifect a single strong rigid structure, securely attached to one of the chain links and extending there- Specification of Letters Patent.

from toward the side walls of the trough in which the conveyer operates.

h To the above purposes my invention consists 1n ce tain novel features of construction herei after more fully described and claimed.

Referring by numerals to the accompanying drawings, 1 designates a trough through which the refuse lumber and saw dust is conveyed and arranged in suitable bearings at the outer end of said trough 1s a drum or sheave 2, around which the chain 3 passes. i

Formed in the bottom of the trough 1 is a longitudinally disposed groove 1a through which the lower port-ions of the vertical links of the chain travel during operation. The main body port-ions A and B'of my improved flight are alike in structurethat is each part is composed of a vertically disposed web 4, and a horizontally disposed web 5. The two webs of each part are cast integral, and if desired strengthening ribs 4" may be formed integral with the rear sides of said webs. y

The under sides of the webs 5 are flat, and are designed to ride directly upon the surface of the bottom'` of the trough l, and the front faces of the webs 4 engage the refuse lumber, and saw dust and force the same forward through the trough to the discharge end thereof. The inner end of the web 5, of the part A is enlarged or thickened as designated by 6, and formed in the under side of this enlarged inner end lportion is a recess 7. Formed through the central portion of the enlarged inner end of this web 5 is an aperture 8 adapted to receive the rivet or like fastening device used for fastening the two parts of the flight together as hereinafter more fully described. Formed integral with the inner end of the enlarged portion 6 and with the inner end of the vertical web 4 of the part A is a head 9, which is transversely disposed with respect to the length .of said part A, and formed in the top of this head 9 is a groove 10, adapted to receivethe upper portion of the link to which the flight is attached. Formed integral with the inner ends of the webs 4 and 5 of the part B is a transversely disposed head 11 designed to fit snugly immediately beneath the head 10, and formed vin the under side of this head 11 is a groove l2 adaptedto receive the lower portion of the link to which the flight is attached. Formed integral with the head 11 on the side opposite the side to which the web 5 is attached is a tongue 13 which is adapted to fit snugly within the recess 7 and formed through the center of said tongue 13 is an apert-ure 14 which when the parts are properly assembled coincides with the aperture 8.

15 designates the rivet or like device used in fastening the two parts of the flight together vand upon the chain, and the lower end of this lever is preferably counter-sunk in a V corresponding portion of the aperture 14. The under side of the head 9 is formed on'a compound curve as clearly shown in Fig. 3 and indicated X X, and the corresponding inner end of the part B is formed on'a compound curve, and thus when the two parts are properly assembled their meeting inner ends fit snugly together.

In assembling the two parts of the flight on the conveyer chain, the part A is manipulated so that the upper portion of the link to which the flight is to be attached is seated inthe groove 10 after which the chain is twisted slightly so as to swing the lower portion of the engaged link upward into approximately the position shown by dotted lines I), Fig. 5. The tongue 13 of the part B is now linserted through the link as shown by dotted lines c, Fig. 5, and said link is now permitted to swing back to a vertical position, and in so doing the part B is manipulated so as to engage t-he lower part of the engaged link in the groove 12, and with the parts so positioned, or as shown by dotted lines d, Fig. 5 the head 11 will travel around beneath the head 9 unt-il the two parts A and B are in alinement and the tongue 13 occupies the recess 7. The rivet 15 is now inserted through the coinciding apertures 8 and 14, and when said rivet is properly secured the two parts of the flight are rigidly connected to one another and to the engaged link of the con-` veyer chain.

The meeting ends of the two parts of the flight are so formed as to overcome all lost motion or play when said two parts are fitted together upon a chain link, and when said two parts are joined by the rivet or like fastening device a very strong, rigid flight is formed which-readily performs the work required.

In chain conveyers of the type herein sho-wn and described it very frequently happens that one of the flights becomes broken and where flights of my improved const-ruction are made use of, a broken flight can be removed and replaced by a new flight without removing the chain from the trough. It will be readily understood that the last mentioned advantage is especially desirable, inasmuch as where the two parts of a flight lare moved longitudinally relative one another in being positioned on the chain, such action can not bevbrought about without removing the chain from the trough or lifting a portion thereof above the top of said trough, and this procedure involves considerable time and labor.

It will be readily understood that minor changes in the formand size of the various parts of my improved flight can be readily made and substituted for those herein shown and described without departing from the spirit of my invention, the scope of which is set forth in the appended claims.
